JP-A-2002-55790 describes a system configured to generate and sendbitmap images to a printing device by means of a host computer forprinting, the system including a print spooling means that spoolsdrawing information from a printing application, a decision means thatdetermines the banding direction of bands forming the bitmap image basedon the spooled drawing information and the conveyance direction of theprint medium by the printing device, and a generating means thatgenerates a bitmap image of the spooled drawing information according tothe selected banding direction. The decision means determines thebanding direction in the opposite direction as the conveyance directionof the print medium in the printing device.

The direction of the bands the printing device processes (vertical bandsor horizontal bands) differs according to the type of printing device.However, JP-A-2002-55790 does not address generating and transferringbands of the direction appropriate to the type of printing device. As aresult, printing cannot be processed efficiently according to the typeof printing device.

SUMMARY

The present invention is directed to solving at part of the foregoingproblem, and provides a print control device, a print control method, aprint control program, and a printing system enabling printingefficiently with consideration for the type of printing device.

print control device that communicates with a management device, whichmanages a printing device, including: an acquisition unit configured toacquire from the management device printing device informationindicating whether a printing device the management device manages is afirst printing device, which processes first band data of bands that arelong in a first direction of a print object, or a second printingdevice, which processes second band data of bands that are long in asecond direction intersecting the first direction of the print object; aband data generator configured to determine the length direction of banddata based on the acquired printing device information, and generateband data in the determined length direction from the print object; anda transmitter configured to send the band data to the management device.

In this configuration, the print control device acquires, from themanagement device that manages the printing device, printing deviceinformation indicating the type of printing device (whether the printingdevice is a first printing device or a second printing device),generates band data with a length direction based on the acquiredprinting device information, and sends the band data to the managementdevice. As a result, band data of an orientation appropriate to the typeof printing device is provided to the management device, and subsequentprocessing by the management device and printing device until printingends is more efficient.

A print control device according to another aspect of the invention alsohas: a selector configured to select a printing device to use from amongone or more printing devices the management device manages; theacquisition unit acquiring the printing device information of theselected printing device.

In this configuration the print control device acquires from themanagement device printing device information for the printing deviceselected in response to a user operation, provides to the managementdevice band data of an orientation appropriate to the type of printingdevice selected, and subsequent processing by the management device andselected printing device until printing ends is more efficient.

In a print control device according to another aspect of the invention,the band data generator determines, based on the acquired printingdevice information, the length direction of the band data is the firstdirection when a first printing device is included in the one or moreprinting devices the management device manages; and determines, based onthe acquired printing device information, the length direction of theband data is the second direction when a first printing device is notincluded in the one or more printing devices the management devicemanages.

In this configuration, when there is at least one first printing deviceamong the printing devices managed by the management device, using thefirst printing device for printing is prioritized, and band data of anorientation appropriate to a first printing device is supplied to themanagement device. As a result, processing by the management device whena first printing device is used for printing is more efficient. Inaddition, when even one first printing device is not included in theprinting devices managed by the management device, band data of anorientation appropriate to a second printing device is supplied to themanagement device. As a result, processing by the management device ismore efficient.

In a print control device according to another aspect of the invention,the printing device information is information indicating whether aprinting device is a first printing device that prints by multipleprintheads disposed in a direction intersecting the conveyance directionof the print medium, or is a second printing device that prints byscanning a printhead in a direction intersecting the conveyancedirection of the print medium, and the conveyance direction of the printmedium is the first direction, and the direction intersecting theconveyance direction is the second direction.

This configuration enables providing to the management device band datain the appropriate orientation according to whether the printing deviceis a first printing device that prints with a line printhead, or is asecond printing device that prints with a serial printhead.

In a print control device aspect of the invention, the printing deviceinformation includes media orientation information indicating theorientation of the print medium set in the printing device; and the banddata generator determines the length direction of the band data based onwhether the acquired printing device information indicates a firstprinting device or second printing device, and the media orientationinformation.

This configuration enables the print control device to provide to themanagement device band data in an orientation appropriate to the type ofprinting device and the orientation of the print medium set in theprinting device, and can improve processing efficiency by the managementdevice.

The technical concept of the invention can be expressed by means otherthan a physical object such as a print control device. For example, theinvention can also be expressed as a method (print control method) ofsteps executed by parts of the print control device, as a program (printcontrol program) causing a computer to execute the method, and as acomputer-readable recording medium (storage medium) storing the program.

The invention can also be embodied by devices equivalent to a managementdevice and printing device, individual methods and programs, and systemsincluding multiple devices.

For example, the invention may also be characterized as a printingsystem including a printing device and a management device that managesthe printing device, wherein: the printing device includes anauthentication request receiver configured to receive an authenticationrequest by a user operation, and send the received authenticationrequest to the management device, and a print mechanism configured toprint based on received print data; and the management device includesan authentication unit that determines whether or not to permit printingin response to the authentication request when an authentication requestis received, and a print data generator configured to generate, from thefirst band data, first print data in which the first direction is thelength direction and send the generated first print data to the printingdevice authenticated for printing, when the printing device theauthentication unit authenticates for printing is a first printingdevice that processes first band data segmented with a first directionof the print object the length direction, and when the printing devicethe authentication unit authenticates for printing is a second printingdevice that processes second band data segmented with a seconddirection, which intersects the first direction of the print object, asthe length direction, converts the first band data to second band data,generates from the converted second band data second print data in whichthe second direction is the length direction, and sends the generatedsecond print data to the printing device authenticated for printing.

This configuration presumes that the printing device that sends anauthentication request in response to a user operation to the managementdevice is a first printing device, and the management device has banddata (first band data) of an orientation appropriate to the firstprinting device. As a result, when printing through the first printingdevice is allowed by the authentication unit, downstream process is moreefficient.

DESCRIPTION OF EMBODIMENTS

Preferred embodiments of the present invention are described below withreference to the accompanying figures. Note that the accompanyingfigures are for descriptive purposes only.

1. System Configuration

FIG. 1 is a simplified block diagram of a system 1 according to theinvention. At least part of this system 1 is a printing system. Thesystem 1 includes a client terminal 10, a management server 20, and oneor more printers (printers 30 and 40 in this example). The printers 30and 40 are examples of printing devices, and the management server 20 isan example of a management device that manages the printing devices. Theclient terminal 10 is an example of a print control device thatcommunicates with the management device.

The client terminal 10 may be a personal computer (PC), smartphone,tablet terminal, mobile phone, or other communication terminal withcomparable capabilities. Hardware capable of embodying the clientterminal 10, and particularly the controller 11, may also be referred toas a print control device.

The management server 20 is embodied by one or more informationprocessing devices that function as a server on a network.

The printers 30 and 40 are devices that function as at least a printer,and may be a multifunction device having other functions such as ascanner or fax machine. Note that the example shown in FIG. 1 has twoprinters 30 and 40, but the number of printers managed by the managementserver 20 is obviously not specifically limited.

The client terminal 10, management server 20, and printers 30 and 40 areconnected to a network 60, and can communicate with other devicesthrough the network 60. The network 60 may be a local area network(LAN), the Internet, a cell phone network, or other type ofcommunication network.

The client terminal 10 includes, for example, a controller 11, display17, operation receiver 18, and communication interface 19. Thecontroller 11 includes one or more IC chips such as a CPU 11 a, ROM 11b, RAM 11 c, or other memory devices. The controller 11 executesprocesses according to programs stored in ROM 11 b using RAM 11 c asworking memory, for example, and thereby controls operation of theclient terminal 10. The controller 11 has a program P1, and by runningthe program P1 executes the functions of a selector 12, informationacquisition unit 13, band data generator 14, and communicationcontroller 15. The program P1 may be referred to as a printer driver orprint control program, for example.

The communication interface 19 is a general term for an interfacethrough which the controller 11 communicates with external devicesthrough the network 60 according to a specific communication protocol.

The display 17 is a means of presenting information visually, and may bean LCD device or OLED device, for example. The display 17 may be aconfiguration including a display and a drive circuit for driving thedisplay.

The operation receiver 18 is a means of receiving user operations, andmay be include physical buttons, a touch panel, a mouse, or a keyboard,for example. The touch panel may obviously also be configured as part ofthe display 17. The display 17 and operation receiver 18 combined mayalso be referred to as the operating panel of the client terminal 10.

The management server 20 includes, for example, a controller 21,communication interface 25, and storage 26. The controller 21 includesone or more IC chips such as a CPU 21 a, ROM 21 b, RAM 21 c, or othermemory devices. The controller 21 executes processes according toprograms stored in ROM 21 b using RAM 21 c as working memory, forexample, and thereby controls operation of the management server 20. Thecontroller 21 has a program P2, and by running the program P2 executesthe functions of a authenticator 22, print data generator 23, andcommunication controller 24. The program P2 may be referred to as aprint manager program, for example.

The communication interface 25 is a general term for an interfacethrough which the controller 21 communicates with external devicesthrough the network 60 according to a specific communication protocol.

The storage 26 may be a hard disk drive or other data storage means. Auser database 27 and printer information 28, for example, are stored inthe storage 26.

Printer 30 includes a controller 31, operation receiver 32, and printmechanism 33, and printer 40 includes a controller 41, operationreceiver 42, and print mechanism 43. In the printer 30 (40), thecontroller 31 (41) controls operation of the printer 30 (40) by thecooperation of hardware and a program (firmware). The print mechanism 33(43) is a mechanism for printing based on print data sent to the printer30 (40) from the management server 20 through the network 60. Theoperation receiver 32 (42) is functionally similar to the operationreceiver 18 described above. The operation receiver 32 (42) may also bean operating panel including a display.

FIG. 2 schematically illustrates part of the print mechanism 33 (FIG. 1)of the printer 30. The print mechanism 33 has a long printhead unit 34.The printhead unit 34 is stationary in the print mechanism 33, and is aunit of multiple printheads 35 aligned in direction D2 a intersectingthe conveyance direction (direction D1 a) of the print medium M. In FIG.2 and FIG. 3, intersecting basically means perpendicular, bitperpendicular as used herein does not mean precisely mathematicallyperpendicular, and includes intersections that may deviate fromperpendicular in products such as printers.

The individual printheads 35 may also be referred to as head chips. Eachprinthead 35 has multiple nozzles for ejecting ink or other fluid. Inthe example in FIG. 2, the shape of the nozzle face through which thenozzles open in each printhead 35 is a parallelogram having sidesinclined to direction D1 a and sides parallel to direction D2 a. Therelationship between the multiple printheads 35 and the printhead unit34 in each printhead 35 may be the same as the configuration of themultiple recording heads and head units described in FIG. 4 ofJP-A-2017-140812.

Note that the plane shape of the nozzle face of the printhead 35 is notlimited to a parallelogram, and may be rectangular, trapezoidal, orother polygonal shape. By aligning multiple printheads 35 in directionD2 a, a printhead unit 34 capable of printing across the full width (thewidth on direction D2 a) of the print medium M conveyed in direction D1a. The printhead unit 34 may also be referred to as a line printhead.

The printer 30 prints using the entire printhead unit 34 prints bydriving the individual printheads 35 based on band data (part of theprint data) for bands that are long in direction D1 a. In thisembodiment of the invention, the conveyance direction of the printmedium M is referred to as the first direction, and the directionintersecting the conveyance direction is referred to as the seconddirection.

Printer 30 is therefore an example of a first printing device thatprocesses first band data dividing the print object into bands that arelong in the first direction of the print object.

FIG. 3 illustrates part of the print mechanism 43 (FIG. 1) of printer40. This print mechanism 43 has a printhead 44 that movesbidirectionally on a carriage not shown. The printhead 44 can movebidirectionally in direction D2 b intersecting the conveyance directionof the print medium M (direction D1 b). Like the printhead 35 describedabove, printhead 44 has multiple nozzles that can eject ink or otherfluid. By the printhead 44 moving (scanning) along the direction D2 b,the printhead 44 can print across the full width of the print medium M(the width in direction D2 b). This printhead 44 is also referred to asa serial printhead.

This printer 40 prints in scanning units by driving the printhead 44during each scan based on band data (part of the print data) for bandsthat are long in direction D2 b while alternately conveying (feeding)the print medium M in the direction D1 b and moving the printhead 44 indirection D2 b.

Printer 40 is therefore an example of a second printing device thatprocesses second band data dividing the print object into bands that arelong in the second direction intersecting the first direction of theprint object.

While not shown in the figures, the print mechanism 33 (43) also has aconveyance mechanism for conveying the print medium M in the conveyancedirection.

It will also be obvious that the client terminal 10, management server20, and printers 30 and 40 also have various general functions andabilities of common personal computers, servers, and printers. Note alsothat all of the content shown in FIG. 1 is not necessarily essential tothe embodiments described below.

2. Embodiment 1

FIG. 4 is a flow chart of the print control process (print controlmethod) the controller 11 of the client terminal 10 executes accordingto program P1 in a first embodiment of the invention.

The controller 11 (selector 12) selects the printer to print the printobject from among the one or more printers managed by the managementserver 20 (step S100). In this first embodiment of the invention, theselector 12 selects the printer in response to a user operation

For example, the selector 12 presents on the display 17 a printerselection screen (not shown in the figure) listing the one or moreprinters the management server 20 manages. By the communicationcontroller 15 communicating with the management server 20 through thecommunication interface 19 before displaying the printer selectionscreen, the controller 11 can acquire from the management server 20information (printer information 28) related to the printers themanagement server 20 manages.

The printer information 28 is information identifying the model, name(product name), serial number, or other information about each printerthe management server 20 manages, and is stored in the storage 26 of themanagement server 20. Based on the printer information 28 acquired fromthe management server 20, the selector 12 generates a printer selectionscreen listing the name, model, or other features of each printer themanagement server 20 manages, and presents the generated printerselection screen on the display 17. The information related to theprinters 30 and 40 can be read in the printer selection screen. Byoperating the operation receiver 18, the user selects the desiredprinter from among the printers listed in the printer selection screenshown on the display 17. Based on the selection by the user, theselector 12 then selects the printer (receives the user's selection of aprinter).

In step S110, the controller 11 (information acquisition unit 13) getsthe printer information related to the printer selected in step S100. Bydisplaying a printer selection screen, the controller 11 thus acquiresfrom the management server 20 the printer information 28 alreadyregistered for printers the management server 20 manages. In step S110,the information acquisition unit 13 acquires (extracts) the printerinformation related to the printer selected in step S100 from theprinter information 28 acquired from the management server 20 for eachprinter.

As described above, the printer information 28 contains type (model)information for each printer the management server 20 manages. This type(model) information may be said to include information that directly orindirectly identifies whether a particular printer is a first printingdevice or a second printing device. Therefore, by step S110 (or stepsS100, S110), the information acquisition unit 13 (or communicationcontroller 15 and information acquisition unit 13) can be said tofunction as an information acquisition unit that acquires from themanagement server 20 printing device information indicating whether aprinter managed by the management server 20 is a first printing deviceor a second printing device.

In step S120, the controller 11 (band data generator 14), based on theprinter information acquired in step S110, determines the lengthwisedirection of the band data to generate, and the process branches basedon the decision. When the printer information acquired in step S110 (theprinter information for the printer selected in step S100) indicates theprinter is a first printing device, the band data generator 14determines the lengthwise direction of the band data is the firstdirection, that is, is the same as the conveyance direction of the printmedium, and goes to step S130. If the printer information acquired instep S110 (the printer information for the printer selected in stepS100) indicates the printer is a second printing device, the band datagenerator 14 determines the lengthwise direction of the band data is thesecond direction, that is, crosswise to the conveyance direction of theprint medium, and goes to step S140.

When control goes to step S130, the band data generator 14 generatesfrom the print object band data that is long in the conveyance directionof the print medium.

When control goes to step S140, the band data generator 14 generatesfrom the print object band data that is long in the direction crosswiseto the conveyance direction of the print medium.

FIG. 5 describes specific examples of step S130 and S140 (band datagenerating process).

Reference PO indicates a one-page print object (print object page PO). Aprint object is data describing an object such as text, a photograph, ora computer graphic, and while not described in detail, and is selectedas desired by the user operating the operation receiver 18. The printobject page PO is bitmap data acquired by rendering the print object,and in this example has RGB (red, green, blue) gradation values, forexample, for each pixel. The band data generator 14 generates band datafor plural bands from the print object page PO. Note that therelationship between the orientation of the print object page PO, andthe direction (direction D1 a, D1 b, and direction D2 a, D2 b) in whichthe print object page PO is printed by the printer, are shown togetherin FIG. 5.

By dividing the print object page PO into bands of a specific band widthin the direction (direction D2 a, D2 b) crosswise to the conveyancedirection in step S130, the band data generator 14 sequentiallygenerates left to right from one side to the other side of the pagefirst band data BD1 that is long in the conveyance direction (directionD1 a, D1 b). The band width (pixel count) of the first band data BD1 theband data generator 14 generates in step S130 is a length equivalent tothe width in direction D2 a of the printheads 35 (FIG. 2) forming theprinthead unit 34 of the first printing device (printer 30). The printerinformation includes information indicating the band width of theparticular printer.

The first band data BD1 may also be described as an area of multiplesets of raster data (lines of raster data) in the conveyance directionof the print object page PO (data of multiple pixels arrayed in aspecific direction).

By dividing the print object page PO into bands of a specific band widthin the conveyance direction (direction D1 a, D1 b) in step S140, theband data generator 14 sequentially generates second band data BD2 thatis long in the direction intersecting the conveyance direction(direction D2 a, D2 b) from the top to the bottom of the page. The bandwidth (pixel count) of the second band data BD2 the band data generator14 generates in step S140 is a length equivalent to the width indirection D1 b of the printhead 44 (FIG. 3) of the second printingdevice (printer 40).

The second band data BD2 may also be described as an area of multiplesets of raster data (lines of raster data) intersecting the conveyancedirection of the print object page PO.

Note that because in FIG. 5 the vertical (top-bottom) direction of theprint object page PO corresponds to the conveyance direction (directionD1 a, D1 b), and the horizontal (left-right) direction of the printobject page PO corresponds to the direction intersecting the conveyancedirection (direction D2 a, D2 b), the first band data BD1 generated instep S130 may be referred to as vertically long (or simply vertical)band data, and the second band data BD2 generated in step S140 may bereferred to as horizontally long (or simply horizontal) band data.

In step S150 (FIG. 4), the controller 11 (communication controller 15)sends the generated band data through the communication interface 19 tothe management server 20. The communication controller 15 andcommunication interface 19 are equivalent to a transmitter that sendsband data to the management server. Note that each time a band of banddata is generated by the band data generator 14, the generated band datais sent sequentially to the management server 20. Therefore, whencontrol goes from step S120 to step S130, first band data BD1 isgenerated in step S130, and the first band data BD1 is transmitted instep S150, this sequence of steps repeats until first band data BD1 isgenerated and transmitted for all of the print object (indicated by thedotted line in FIG. 4).

Likewise, when control goes from step S120 to step S140, second banddata BD2 is generated in step S140, and the second band data BD2 istransmitted in step S150, this sequence of steps repeats until secondband data BD2 is generated and transmitted for all of the print object(indicated by the dot-dot-dash line in FIG. 4).

Note that the band data generator 14 adds to the band data generated asdescribed above printer identification information (such as the serialnumber of the printer) uniquely identifying the printer selected in stepS100. In addition, the band data generator 14 adds to the last band datagenerated from the print object information indicating it is the lastband data for that print object.

Note also that the band data generator 14 may, for example, compress thegenerated band data to lighten the communication load of transmission tothe management server 20.

FIG. 6 is a flow chart of the print management process (print managementmethod) the controller 21 of the management server 20 executes accordingto the program P2 in the first embodiment of the invention.

The controller 21 (communication controller 24) repeatedly determineswhether or not band data was received from the client terminal 10through the communication interface 25 (step S200), and if band datasent from the client terminal 10 was received (step S200 returns Yes),goes to step S210.

In step S210, the controller 21 (print data generator 23) executes aband data conversion process on the band data determined in step S200 tohave been received. In the band data conversion process, the band datais converted to band data in a specific command code systeminterpretable by the printer identified by the printer identificationinformation added to the band data (the printer selected in step S100).For example, the print data generator 23 adds commands in the commandcode system that the printer identified by the printer identificationinformation added to the band data can interpret, or applies acompression process dependent on the command code system, to each banddata object. The band data resulting from this conversion process isalso referred to as the print data (part of the print data).

When processing first band data BD1, the print data generator 23 uses acommand code system such as ESC/Page as the command code system that canbe interpreted by the printer (first printing device) identified by theprinter identification information added to the first band data BD1.

When processing second band data BD2, the print data generator 23 uses acommand code system such as ESC/P-R as the command code system that canbe interpreted by the printer (second printing device) identified by theprinter identification information added to the second band data BD2.

The first band data BD1 is still vertical band data after conversion instep S210, and the second band data BD2 is still horizontal band dataafter conversion in step S210.

In step S220, the controller 21 (communication controller 24) sends theband data (print data) after conversion in step S210 through thecommunication interface 25 to the printer identified by the printeridentification information added to the band data (the printer selectedin step S100).

In step S230, the controller 21 determines if the band data justprocessed in steps S210 and S220 is the last band data to process, andif it is the last band data, determines the last band data has beenprocessed, that is, determines that processing all print objects iscompleted (step S230 returns Yes), and ends the flow chart in FIG. 6.

However, if the band data just processed in steps S210 and S220 is notthe last band data, the controller 21 determines the last band data hasnot been processed (step S230 returns No), and returns to step S200.

By repeatedly cycling through steps S200 to S230, the controller 21 canapply the required conversion process to the band data objectssequentially transmitted from the client terminal 10 as the individualprocess units, and sequentially send the converted band data to theprinter.

The printer receiving the converted band data from the management server20 through the network 60 interprets the commands contained in thereceived band data, applies other required conversion processes (such asconverting the resolution of the band data, converting the color system,half-toning), and prints based on the band data.

In other words, the printer 30 (first printing device) sequentiallyreceives converted first band data BD1 from the management server 20,and when one page of first band data BD1 is received, the controller 31simultaneously drives the multiple printheads 35 in first band data BD1units to print the page (print objects) on the print medium M. At thistime, the controller 31 drives the printheads 35 while adjusting thewidth (pixel count) of the first band data BD1 as required according tothe width (nozzle count) of the printheads 35, for example.

In printer 40 (second printing device), however, the controller 41,while sequentially receiving the converted second band data BD2 from themanagement server 20, controls driving each scan of the printhead 44 insecond band data BD2 units to print the print objects on the printmedium M.

3. Embodiment 2

FIG. 7 is a flow chart of the print control process (print controlmethod) the controller 11 of the client terminal 10 executes accordingto program P1 in a second embodiment of the invention.

Differences between the second embodiment and the first embodiment aredescribed below, while further description of content common to thefirst embodiment is abbreviated or omitted. In the first embodiment, theclient terminal 10 selects the printer to use for printing the printobject in response to a user operation, and reports the selected printerto the management server 20. In the second embodiment, however, theclient terminal 10 does not select the printer to use for printing theprint object. This means that in the second embodiment the clientterminal 10 generates and transmits band data without knowing whichprinter will used to print the print objects.

The controller 11 (information acquisition unit 13) controls thecommunication controller 15 to communicate with the management server 20through the communication interface 19, and acquires the printerinformation 28 related to the printers the management server 20 managesfrom the management server 20 (step S300). In step S300, the informationacquisition unit 13 (or the communication controller 15 and informationacquisition unit 13) can be said to function as an acquisition unit thatacquires from the management server 20 printing device informationindicating whether a printer managed by the management server 20 is afirst printing device or a second printing device.

In step S310, the controller 11 (band data generator 14), based on theprinter information 28 acquired in step S300, determines if a firstprinting device is included in the one or more printers managed by themanagement server 20. The band data generator 14 references the type(model) information of the printers in the printer information 28, andif at least one of the printers managed by the management server 20 is afirst printing device (such as printer 30) (step S310 returns Yes), goesto step S320.

However, if by referencing the type information of each printer in theprinter information 28 the controller 11 determines a first printingdevice is not included in the printers the management server 20 manages(step S310 returns No), the band data generator 14 goes to step S340.

In step S320, the band data generator 14 determines the length directionof the band data to generate is the first direction, that is, is in theconveyance direction of the print medium, and goes to step S330.

However, in step S340, the band data generator 14 determines the lengthdirection of the band data to generate is the second direction, that is,intersects the conveyance direction of the print medium, and goes tostep S350.

The flow of the process from step S330 to S360, and the flow of theprocess from step S350 to S360, is the same as the flow of the processfrom step S130 to S150, and the flow of the process from step S140 toS150, described above in FIG. 4 and FIG. 5. However, unlike in the firstembodiment, the band data generator 14 does not add printeridentification information for the printer to use for printing to theband data generated in step S330 or step S350.

FIG. 8 is a flow chart of the print management process (print managementmethod) the controller 21 of the management server 20 executes accordingto the program P2 in the second embodiment of the invention.

In the second embodiment the controller 21 of the management server 20determines the printer to use for printing the print object based onaccess from the printer (step S400). In this event, the user operatesthe printer selected from among the printers in the system 1, and sendsa specific request from the printer to the management server 20 throughthe network 60. The management server 20 that receives the request thendetermines that the printer that transmitted the request is the printerto use for printing the print object (step S400).

In the second embodiment, the management server 20 simply identifies theprinter that sends a specific request as the printer to use to print theprint object (the printer to which to send the print data), but thesecond embodiment may be used for authenticated printing as describedbelow.

Part of the flow for authenticated printing is described first belowbefore continuing with the description of the flow in FIG. 8.

By operating the client terminal 10 and inputting previously set useridentification information (information unique to each user authorizedto use authenticated printing, referred to below as the user ID), theuser logs in to the operating system (OS) of the client terminal 10, andstarts the program P1. While executing the process shown in FIG. 7 (stepS330 or step S350), the controller 11 of the client terminal 10 thatruns the program P1 generates band data based on the print objectspecified by the user that logged in (referred to below as the logged-inuser), and sends the generated band data to the management server 20(step S360). At this time, the controller 11 (band data generator 14)adds the user ID of the logged-in user to the generated band data.

The controller 21 of the management server 20 stores the band data witha user ID received by the communication interface 25 through the network60 to the storage 26, for example, in the order received. Userinformation for each authorized user is previously stored in a userdatabase 27 in the storage 26. The user information includes the userID, or personal information other than the user ID (such as the name ore-mail address), for each user.

The user operates the printer (printer 30 in this example) selected fromamong the printers in the system 1, and inputs the user ID. Thecontroller 31 of the printer 30 that received input of the user IDthrough the operation receiver 32 then sends an authentication requestincluding the input user ID through the network 60 to the managementserver 20. In other words, the action of inputting the user ID to theprinter is equivalent to a user authentication request. The printer cantherefore be said to have an authentication request receiver (theoperation receiver 32 and controller 31, for example) that receives anauthentication request through a user operation, and sends the receivedauthentication request to the management server 20.

The controller 21 (authenticator 22) of the management server 20 thatreceived the authentication request then verifies, in response to theauthentication request, whether or not to allow printing. Theauthenticator 22 decides to allow printing (determines authentication issuccessful) if the user ID contained in the received authenticationrequest matches a user ID for a user registered in the user database 27.As a result, the user that input the user ID to the printer isauthenticated by the management server 20 as a user that is allowed touse the printer. The authenticator 22 then determines that the printerthat sent the authentication request that was verified to allow printingis the printer to use for printing the print job (step S400). In otherwords, in the second embodiment, the management server 20 can determinein step S400 based on access (an authentication request) from theprinter to use that printer to print the print job.

Note that when the user ID contained in the received authenticationrequest does not match the user ID of a user registered in the userdatabase 27, the authenticator 22 determines to not allow printing(authentication fails). When in authenticated printing the authenticator22 determines to not allow printing, the authenticator 22 ends theprocess of the flow chart in FIG. 8 without identifying a printer to usefor printing the print job in step S400.

If the printer to use for printing the print object is determined instep S400, in step S410 the controller 21 (print data generator 23)determines if the printer identified in step S400 is a first printingdevice, and if the printer is a first printing device (step S410 returnsYes), goes to step S420.

However, if the printer identified in step S400 is a second printingdevice (step S410 returns No), control goes to step S450.

In step S420 and step S430, the print data generator 23 sequentiallyprocesses, in first-in, first-out order of being stored to the storage26, the band data that is stored in the storage 26 and contains a userID matching the user ID contained in the authentication request forwhich printing was allowed by the authentication process describedabove. Steps S420 and step S430 basically conform to step S210 and stepS220 (FIG. 6) described above.

That the printer selected in step S400 is a first printing device (forexample, printer 30) means that there is at least one first printingdevice included in the printers managed by the management server 20(that is, in FIG. 7, step S310 returned Yes). Therefore, when controlgoes to step S420 based on the decision of step S410, the managementserver 20 always receives from the client terminal 10 first band dataBD1 that is long in the conveyance direction of the print medium(vertical band data), and stores the received first band data BD1 in thestorage 26.

As a result, in step S420, the print data generator 23 executes the banddata conversion process on the first band data BD1. In this case, theprint data generator 23 converts the first band data BD1 to band datausing a specific command code system that the printer (first printingdevice) identified in step S400 can interpret. Then in step S430, thecommunication controller 24 sends the first band data BD1 (print data)after conversion in step S420 to the printer (first printing device)identified in step S400 through the communication interface 25.

In step S440, the controller 21 determines if the first band data BD1processed in the most recent step S420 and S430 is the last band data(is the last first band data BD1 containing a user ID matching the userID contained in the authentication request permitted to print by theauthentication process described above), and if it is the last banddata, determines that processing all print objects is completed (stepS440 returns Yes), and ends the flow chart in FIG. 8.

However, if the band data just processed in steps S420 and S430 is notthe last band data BD1, the controller 21 determines the last band datahas not been processed (step S440 returns No), and returns to step S420.

In step S450 and step S460, the print data generator 23 sequentiallyprocesses, in first-in, first-out order of being stored to the storage26, the band data that is stored in the storage 26 and contains a userID matching the user ID contained in the authentication request forwhich printing was allowed by the authentication process describedabove. However, step S450 differs from step S420 in that the lengthdirection of the band data may be converted.

That the printer selected in step S400 is a second printing device (forexample, printer 40) means that there may be at least one first printingdevice included in the printers managed by the management server 20(that is, in FIG. 7, step S310 returned Yes), or that a first printingdevice is not included in the printers managed by the management server20 (that is, in FIG. 7, step S310 returned No).

Therefore, when control goes from step S410 to step S450, the band datasent from the client terminal 10 and stored in the storage 26 of themanagement server 20 is first band data BD1 that is long in theconveyance direction of the print medium (vertical band data), or issecond band data BD2 that is long in a direction intersecting theconveyance direction of the print medium (horizontal band data).

When control goes from step S410 to step S450, the printer identified instep S400 is a second printing device, and the print data generator 23requires second band data BD2 for processing. If the band data stored inthe storage 26 is second band data BD2, the print data generator 23executes a band data conversion process for second band data BD2 storedin the storage 26. In other words, the print data generator 23 convertsthe second band data BD2 to band data using a specific command codesystem interpretable by the printer identified in step S400 (secondprinting device).

However, if the band data stored in the storage 26 is first band dataBD1, in step S450 the print data generator 23 first converts thelengthwise direction of the band data, and then converts the band datato band data in a specific command code system the printer (secondprinting device) identified in step S400 can interpret.

FIG. 9 illustrates the process of step S420 and the process of stepS450. FIG. 9A illustrates the process of step S420.

In step S420, the print data generator 23 reads and processes the firstband data BD1 (band data having a user ID matching the user ID containedin the authentication request authenticated for printing in theauthentication process described above) stored in the storage 26 onesegment at a time, adds a command C1 corresponding to the command codesystem the first printing device can interpret, and generates convertedfirst band data BD1 (print data).

FIG. 9B is the process of step S450 when the band data stored in thestorage 26 is horizontal band data BD2. In other words, if the band data(band data having a user ID matching the user ID contained in theauthentication request authenticated for printing in the authenticationprocess described above) stored in the storage 26 is second band dataBD2, in step S450 the print data generator 23 reads and processes thesecond band data BD2 one segment at a time, adds a command C2corresponding to the command code system the second printing device caninterpret, and generates converted second band data BD2 (print data).

FIG. 9C is the process of step S450 when the band data stored in thestorage 26 is vertical band data BD1. In other words, if the band data(band data having a user ID matching the user ID contained in theauthentication request authenticated for printing in the authenticationprocess described above) stored in the storage 26 is first band dataBD1, in step S450 the print data generator 23 remerges the first banddata BD1 to restore the print object page PO, and then slices the printobject page PO from top to bottom to extract horizontal second band dataBD2. In this case, the last band data BD2 extracted from the printobject page PO is the last band data. As a result, the lengthwisedirection of the band data is converted (changed from vertical tohorizontal bands). The print data generator 23 then selects the secondband data BD2 after converting the length direction for processing, addsa command C2 corresponding to the command code system the secondprinting device can interpret to the second band data BD2, and generatesconverted second band data BD2 (print data).

In step S460 (FIG. 8), the communication controller 24 sends the secondband data BD2 (print data) resulting from step S450 through thecommunication interface 25 to the printer (second printing device)identified in step S400.

In step S470, the controller 21 determines if the second band data BD2processed in the most recent step S450 and S460 is the last band data,and if it is the last band data, determines that processing all printobjects is completed (step S470 returns Yes), and ends the flow chart inFIG. 8.

However, if the band data just processed in steps S450 and S460 is notthe last band data BD2, the controller 21 determines the last band datahas not been processed (step S470 returns No), and returns to step S450.

The printer that receives the converted band data from the managementserver 20 through the network 60, that is, the printer identified instep S400 to use for printing the print object, then interprets thecommands added to the received band data, applies other requiredconversion processes (such as converting the resolution of the banddata, converting the color system, half-toning), and prints based on theband data.

As a result, the printer authorized by the management server 20 for useprinting in response to an authentication request resulting from a useroperation can print a print job linked to the user based on print datasent from the management server 20 (can execute authenticated printing).

4. Summary

A client terminal 10 that communicates with a management server 20 thatmanages multiple printers 30 and 40 in this embodiment of the inventionexecutes an acquisition process (step S100, S110, S300) of acquiringfrom the management server 20 printer information indicating whether aparticular printer the management server 20 manages is a first printingdevice that processes first band data (band data BD1) for bands that arelong in a first direction of the print object (the conveyance directionof the print medium), or is a second printing device that processessecond band data (band data BD2) for bands that are long in a seconddirection intersecting the first direction; a band data generatingprocess (step S120, S130, S140, S310, S320, S330, S340, S350) ofdetermining the length direction of the band data based on the acquiredprinter information, and generating band data of the determined lengthdirection from the print object; and a transmission process (step S150,S360) of sending the band data to the management server 20.

When management server 20 manages multiple types of printers, such as afirst printing device and a second printing device, the client terminal10 in this configuration can provide band data in the orientationappropriate to the type of printer to the management server 20. As aresult, downstream processing by the management server 20 to completeprinting, and printing by the printer, are more efficient.

In the first embodiment described above, the client terminal 10 selectsthe printer to use for printing from among the one or more printers themanagement server 20 manages (step S100), and acquires printerinformation for the selected printer (step S110). This configurationenables providing to the management server 20 band data in theorientation (first band data BD1 or second band data BD2) appropriate tothe type of printer selected in response to a user operation (either afirst printing device or second printing device). As a result, themanagement server 20 can efficiently execute the conversion processesrequired to generate the band data to be sent to the selected printer.

In the second embodiment, when the client terminal 10 determines a firstprinting device is included in the one or more printers the managementserver 20 manages based on printer information 28 acquired from themanagement server 20 (step S310 returns Yes), the client terminal 10determines the length direction of the band data is a first direction(conveyance direction of the print medium) (step S320); and when theclient terminal 10 determines a first printing device is not included inthe one or more printers the management server 20 manages based onprinter information 28 acquired from the management server 20 (step S310returns No), the client terminal 10 determines the length direction ofthe band data is a second direction (a direction intersecting theconveyance direction of the print medium) (step S340).

In other words, when the printers the management server 20 managesinclude even only one first printing device, the client terminal 10assumes that using a first printing device for printing is preferred,and provides to the management server 20 first band data BD1 of anorientation appropriate to a first printing device. As a result, whenthe management server 20 actually determines in step S400 to use a firstprinting device for printing, conversion and other processing by themanagement server 20 can be made more efficient. The second embodimentcan therefore be said to be particularly effective in an environment inwhich a relatively large number of first printing devices, also known aspage printers, are used. When the printers the management server 20manages do not include even one first printing device, the clientterminal 10 provides to the management server 20 second band data BD2 ofan orientation appropriate to second printing devices, and makesconversion and other processing by the management server 20 moreefficient.

In the second embodiment, the printer has an authentication requestreceiver (such as the operation receiver 32 and controller 31 of printer30, or the operation receiver 42 and controller 41 of printer 40) thatreceives an authentication request through a user operation and sendsthe received authentication request to the management server 20; and aprint mechanism (33, 43) that prints based on print data sent thereto.

The management server 20 has an authenticator 22 that, when anauthentication request is received, determines whether or not printingis allowed by the authentication request; and a print data generator(print data generator 23 and communication controller 24). When theprinter authenticated by the authenticator 22 for use printing is afirst printing device (step S410 returns Yes), the print data generatorgenerates first print data (band data BD1 after conversion) that is longin a first direction from the first band data (band data BD1) and sendsthe generated first print data to the printer authenticated for printing(step S420, S430). When the printer authenticated by the authenticator22 for use printing is a second printing device (step S410 returns No),the print data generator converts the first band data (band data BD1) tosecond band data (band data BD2), then generates second print data (banddata BD2 after conversion) that is long in a second direction from thesecond band data (band data BD2) (see FIG. 9C), and sends the generatedsecond print data to the printer authenticated for printing (step S450,S460).

This configuration presumes using the system 1 for authenticationprinting, presumes that a printer sending an authentication request tothe management server 20 in response to a user operation is a firstprinting device, and the management server 20 receives and stores banddata BD1 of an orientation appropriate to a first printing device fromthe client terminal 10. As a result, authentication printing can beprocessed efficiently in an environment in which first printing devices,which are a type of page printer, are used relatively often.

Effects of the embodiments thus comprised are described below. That is,by segmenting the data of the print object (print object page PO) intoband data on the client terminal 10 side, and sequentially sending theband data to the management server 20, the management server 20 cansequentially convert and send to the printer the received band data(generate print data) without waiting until the data for a full page isreceived. As a result, compared with the configuration of the relatedart that starts the required processing after a full page of data isreceived, the management server 20 starts processing the data of theprint job more quickly, and the printer can therefore more quickly startprinting based on the print data.

In addition, because the management server 20 in the first embodimentdoes not need to store the band data received from the client terminal10 in page units, memory (storage) can be used more efficiently on themanagement server 20.

5. Other Embodiments

The invention is not limited to the embodiments described above, and canbe varied in many ways.

Variation 1

FIG. 10 illustrates the relationship between a printer 30 that is afirst printing device, and the direction in which the print medium M isset in the printer. A print medium M conveyed in direction D1 a relativeto the printhead unit 34 of the print mechanism 33 can be set in theprinter 30 as indicated by the solid line or the dot-dot-dash line asshown in FIG. 10. The print medium M shown in FIG. 10 is A4 size. LEindicates the long edge of the print medium M, and SE indicates theshort edge. The printer 30 shown in FIG. 10 can convey A4 size paper ina long edge feed (LEF) mode in which the long edge LE is the leadingedge as indicated by the solid line, or a short edge feed (SEF) mode inwhich the short edge SE is the leading edge as indicated by thedot-dot-dash line. Note that while not shown in FIG. 10, the printer 30in this example can also feed A3 size paper, which is equal to two A4size sheets, only in the short edge feed SEF mode due to the physicallimitations of the printer 30. To further simplify description, printer40, which is a second printing device, is a type that can only feed theprint medium M in the short edge feed SEF mode.

Presuming this specific configuration, when A4 size and A3 size paper isfed by the printer 30 in the short edge feed SEF mode, band data BD1,which is long in the conveyance direction of the print medium (from topto bottom of the print object), is generated from the print object asdescribed above, and the printer 30 can be driven to print based on theband data BD1.

When printing with printer 40, band data BD2, which is long in thedirection intersecting the conveyance direction of the print medium(from the left to right side of the print object), is generated from theprint object as described above, and the printer 40 can be controlled toprint based on the band data BD2.

However, when printing A4 size paper in the long edge feed LEF mode onprinter 30, the print object must be rotated 90 degrees for printing,generating band data BD1 that is long from top to bottom of the printobject is not appropriate, and band data BD2, which is long from theleft to right side of the print object, must be generated.

To address this, the printer information 28 includes media orientationinformation indicating the direction in which the print medium is set inthe printer, and the controller 11 (band data generator 14) of theclient terminal 10 determines the length direction of the band data togenerate based on whether the printer is a first printing device or asecond printing device and the media orientation indicated by theacquired printer information 28.

More specifically, the controller 21 of the management server 20acquires from each managed printer information (media orientationinformation) indicating the direction (for short edge feed SEF or longedge feed LEF) in which the print medium is set in the paper tray of theprinter, for example, and the paper size, and stores the acquiredinformation in the printer information 28 as part of the printerinformation for each printer. As a result, the client terminal 10 canknow not only the type of each printer, but also the orientation andsize of the print medium loaded in each printer, by referencing theprinter information 28.

In the first embodiment, the controller 11 of the client terminal 10decides step S120 based on the paper orientation and other information.For example, when printer 30 is selected in step S100, the controller 11gets the printer information for that printer 30 in step S110. If theprinter information for printer 30 indicates the orientation of theprint medium is for short edge feed SEF, and identifies the printer 30as a first printing device, control goes to step S130. However, if theprinter information for printer 30 acquired in step S110 indicates theorientation of the print medium is for long edge feed LEF, andidentifies the printer 30 as a first printing device, the controller 11determines in step S120 that the length direction of the band dataintersects the conveyance direction of the print medium, and controlgoes to step S140. As a result, when control goes to step S140,horizontal band data BD2 (FIG. 5) is generated from the print objecteven though the printer to use for printing is a first printing device(printer 30).

However, if A4 size paper is loaded for long edge feed LEF in theprinter 30, the print object (in this case, the band data) is rotated 90degrees for printing. The printer 30 handles this rotation process.Therefore, even if the band data the client terminal 10 extracts fromthe print object for printer 30 is band data BD2 that is long in thedirection intersecting the conveyance direction of the print medium, theband data BD2 is rotated in the printing process of the printer 30, andis therefore band data that is long in the conveyance direction of theprint medium.

Note that in the second embodiment when the controller 11 of the clientterminal 10 determines in step S310 that a first printing device isincluded in the printers managed by the management server 20, thecontroller 11 references the printer information for one of the firstprinting devices, and branches processing the length direction of theband data to the conveyance direction of the print medium orintersecting the conveyance direction of the print medium based on thepaper orientation setting. Also in the second embodiment, the controller21 of the management server 20 may convert the length direction of theband data as necessary if the orientation of the band data stored in thestorage 26 and the orientation of the band data provided to the printerselected in step S400 do not match.

In this first variation, the client terminal 10 generates and providesto the management server 20 band data in the appropriate orientationbased on not only the type of printer (first printing device or secondprinting device), but also on the orientation of the print medium in theprinter. As a result, processing by the management server 20 is moreefficient, and the printer can be controlled to print appropriately.

Variation 2

FIG. 11 illustrates horizontally long band data BD2 generated from theprint object in step S140 (or step S350). In the embodiment describedabove, the band data generator 14 sequentially generates the band dataBD2 from top to bottom of the print object page PO. In other words, theband data BD2 is generated sequentially in the order indicated by thenumbers on the right side not enclosed in parentheses in FIG. 11, andsent to the management server 20 in the order produced. However, thecontroller 11 in this second variation generates the band data BD2 byalternating from the top to the bottom of the print object page PO. Morespecifically, the band data BD2 is generated in the order indicated bythe numbers in parentheses in FIG. 11, and sent to the management server20 in the order produced.

In a second printing device such as printer 40 that scans a serialprinthead 44 and prints an image of the band data BD2 on the printmedium during each scan, if printing always maintains the originaltop-bottom direction of the print object, the band data BD2 can besequentially generated from top to bottom of the print object page POwith no problem.

However, when printing on both sides of the print medium, the printobject may be rotated 180 degrees top-bottom on one side of the printmedium. When the print object is rotated 180 degrees top-bottom on oneside of the print medium, the band data BD2 (print data) at the bottomend of the band data BD2 for one page must be sent first to the secondprinting device.

However, when the band data BD2 is sequentially generated from the topto the bottom of the print object page PO, the management server 20cannot start conversion processing of the band data BD2 until after theband data BD2 for the bottom end of one page is sent to the managementserver 20, and this is not efficient. In this second variation,therefore, the controller 11 alternately generates band data BD2 fromthe top and bottom sides of the print object page PO, and sends the banddata to the management server 20 in the order produced. As a result,whether the print object is rotated top-bottom or the print object isrotated 180 degrees top-bottom, the management server 20 can quicklystart processing the band data BD2 sent sequentially from the clientterminal 10, and as a result the time when printing by the secondprinting device starts can be reliably accelerated.
